Improved roofing-cement



NITED STATES PATENT OFFIC WILLIAM GREEN, OF CLEVELAND, OHIO.

IMPROVED ROOFING-CEMENT.

' To an whom it may concern:

. Be it known that I, WILLIAM GREEN, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Roofing-Cement; and I do hereby declare that the following is afull and complete description of the materials used, and the manner of compounding and applying the same.

I take pulverized iron ore, either separately or combined with pulverized slate, stone-coal, coke, or other similar substance, or either or any of them, mixed with petroleum-oil, linseedoil, fish-oil, or any other suitable oil to the consistency of a paint, paste, or cement. This I apply with a brush, trowel, or other suitable instrument to paper felt, wood, stone, orvbricks as a plastic cement or paint, as may be desired. It can be used for the roofs or sides of buildings, or for railroad-cars, bridges, Ste.

When used for roofing purposes the compound should be made thicker than when used for paint.

It may be made as thin as desired by the use of turpentine, naphtha, or any other of the light mineral oils.

What I claim as my improvement, and de-' sire to secure by Letters Patent, is

A cement or paint for roofing or other purposes for which it may be adapted, composed WILLIAM GREEN.
